abstract = "Tekstilna industrija spada u red industrija sa najvećom potrošnjom vode u svom
proizvodnom procesu. Opšta karakteristika otpadnih voda iz tekstilne industrije je, pre svega, visok
sadržaj organskih materija i visoka obojenost. Sa aspekta zaštite životne sredine, uslovi za
ispuštanje otpadnih voda su sve strožiji, dok je primena ekološki i ekonomski prihvatljivih
adsorbenata za tretman otpadnih voda veliki izazov današnjice. Upravo zbog toga, u okviru ovog
rada ispitivana je mogućnost primene katjonskih adsorbenata na bazi prirodnog materijala skroba
za uklanjanje metil oranž (MO) boje iz vodenih rastvora. Korišćena su dva derivata katjonskog
skroba, skrob modifikovan sa glicidiltrimetilamonijum hloridom (CS-G) i skrob modifikovan sa
betain hidrohloridom (CS-B). Karakterizacija funkcionalnih grupa na površini materijala izvršena
je korišćenjem infracrvene spektroskopije sa Furijeovom transformacijom (FTIR), dok je
morfologija materijala ispitana pomoću skenirajuće elektronske mikroskopije (SEM). Kako bi se
utvrdili optimalni adsorpcioni uslovi ispitana je kinetika adsorpcije, adsorpcione izoterme, kao i
uticaj pH vrednosti. Na osnovu dobijenih kapaciteta adsorpcije pri optimalnim uslovima, određene
su efikasnosti uklanjanja MO iz vodenih medijuma. Takođe, ispitana je i adsorpcija drugih
anjonskih i katjonskih boja. Ispitivani katjonski skrobovi su se pokazali kao efikasni adsorbenti za
uklanjanje MO i drugih anjonskih (alizarin crveno S, ARS), ali i katjonskih (metilensko plavo, MB i
brilijant zelena, BG) boja iz vodenih rastvora., The textile industry is one of the industries with the highest water consumption in its
production process. The general characteristic of wastewater from the textile industry is, primarily,
the high content of organic matters and high coloration. From the aspect of environmental
protection, the conditions for wastewater discharge are becoming more stringent, while the
application of environmentally and economically acceptable adsorbents for wastewater treatment is
a great challenge today. For this reason, the possibility of using cationic adsorbents based on natural starch material to remove methyl orange (MO) from aqueous solutions was investigated.
Two cationic starch derivatives were used, starch modified with glycidyltrimethylammonium
chloride (CS-G) and starch modified with betaine hydrochloride (CS-B). Surface functional groups
were characterized by Fourier transform infrared spectroscopy (FTIR), while the morphology of
the material was examined using scanning electron microscopy (SEM). In order to determine the
optimal reaction conditions, the kinetics of adsorption, adsorption isotherms, as well as the
influence of pH values were examined. Based on the obtained adsorption capacities under optimal
conditions, the efficiencies of MO removal from aqueous media were determined. The adsorption of
other anionic and cationic dyes was also investigated. The tested cationic starches proved to be
effective adsorbents for the removal of MO and other anionic (alizarin red S, ARS), but also
cationic (methylene blue, MB and brilliant green, BG) dyes from aqueous solutions.",
